Spring Clean Your Eye Health

1.Allergies

The season of spring is not only a sign that the days are getting longer and brighter but also that flowers, plants, trees and grasses begin to come alive again after the cold winter. This may look nice but if you suffer from allergies, such as hay fever, this can play real havoc with your eyes. If you use antihistamines, try to start these early in the year so when hay fever season starts you will already be protected. Also, where possible, try to avoid going outside on high pollen days, but if you have to, as soon as you get back home have a shower/bath and put on fresh clothes to avoid the pollen returning to your eyes from your body and clothes. There are many aids to help your eyes during the hay fever months, getting an appointment with your ophthalmologist to discuss your options is always recommended.

2.Sunglasses

Sunglasses should be worn all year round but many people forgot to wear them during the winter months and wait until the bright summers days to start wearing them again. Make an effort to start wearing your sunglasses earlier this year. During the spring months of March, April and May the days start to get brighter and longer but even when we get those grey days you should try to wear sunglasses when outdoors, it’s a great habit to get into. Long term sun overexposure can play a part in causing some eye problems, such as cataracts, so protecting them earlier will always be best.

3.Diet & Exercise

After the long winter months of possibly less exercise and a poor diet, spring is a perfect way to kick start healthy living again. A healthy diet and exercise is not only great for your general health but is very important to eye health. Foods high in beta-carotene, omega 3, vitamin c and e, and lutein are vital to healthy eyes. Examples of these foods are carrots, pumpkin, oily fish, berries, citrus fruit, almonds, avocados, kale, spinach, and eggs.

4.Rest & Relaxation

Resting and relaxing your eyes is very important in keeping them healthy. If you spend a lot of time looking at a computer screen for example, you could strain your eyes. A great tip is following the 20-20-20 rule; every 20 minutes’ look about 20 feet away for 20 seconds, this can really help prevent your eyes getting tired and strained from over working them. Getting good sleep is another way your eyes need to rest, about 7-8 hours for an average adult is recommended. Placing something warm over closed eye lids, such as a heated eye mask, can really aid in resting and relaxing your tired eyes in the evening, this is also great if you suffer from dry eyes and meibomian gland dysfunction (MGD).

5.Eye Test

The average adult should have an eye test every 2 years and this may be more frequent if you suffer with health or eye problems. Spring is a perfect time to check if you are due for an eye test. If you are looking for a more thorough examination you can get an appointment with an ophthalmologist, their appointments tend to be more detailed and it may include having detailed eye scans (topography) carried out to enable the ophthalmologist to check all parts of your eyes more thoroughly.

Winter Eye Problems

During winter, the weather is colder and windier and this can really dry the eyes, but also when you try to warm up by using heat, such as a blower heater or central heating, this can also dry out the eyes. Some easy tips to help combat this problem is to use artificial tear drops to keep your eyes hydrated throughout the day, drinking plenty of water, and even warm soup, will keep your body and eyes hydrated. Also try to avoid direct heat, especially heat that is blowing directly in your face, like car heaters for example, try to direct the airflow away from your face. If it is a windy day you can use glasses or goggles to help protect your eyes from the wind directly drying out your eyes. If you already suffer from dry eyes it is always a good idea to speak to your ophthalmologist if you are struggling in the winter months, as they will advise what else you can do to keep on top of your dry eyes during winter.

Tearing Eyes

Apart from winter weather drying out your eyes, the cold weather can also make your eyes over produce tears which can be very annoying and can make vision blurry. The best thing to help with this is to wear glasses, goggles, or sunglasses when outside to avoid the wind causing watery eyes. Also, if you are wiping your eyes to get rid of the tears make sure you use clean tissues or cloths to avoid infection. Excessive tearing eyes can also be caused by other factors such as infection, blocked tear duct, or surprisingly dry eyes, so if you are concerned make an appointment with your eye clinic or opticians so they can check it out.

Tired Eyes

The winter months are darker and natural light is less which can make certain tasks more difficult, reading and writing for example. Straining your eyes to see in lower light can cause eyestrain making your eyes feel tired quicker than usual. To help avoid this try having a lamp on when carrying out close work and if you require glasses to see well, make sure you wear them to avoid overstraining your eyes.

Light Sensitive Eyes

The sun tends to be lower in the sky during winter and this can cause difficulty seeing, especially when driving, light sensitivity, and damage caused by UV rays. Try to make a habit of not only wearing sunglasses in the summer, but also the winter. If you drive, keep a spare pair of sunglasses in your car so you are always prepared for the low, bright sun. Sunglasses also protect your eyes from the sun’s harmful UV rays which can contribute to many eye issues, such as cataracts. Make sure your sunglasses are 100% UVA and UVB protected.

Red Eyes

Red eyes can be a sign of many things, such as tiredness, dryness, blurry vision, over tearing, infection, and inflammation. Winter weather can cause eye redness due to many of these factors but also it can be caused from the sunlight either directly or from being reflected on snow for example. This can lead to inflammation of the cornea causing the red eyes, therefore this is another reason why wearing sunglasses or snow goggles is so important in winter.

Transform How You See The World With Lasik Laser Treatment

LASIK is an outpatient refractive surgery procedure. A laser is used to reshape the cornea (the clear, round dome at the front of the eye) to improve the way the eye focuses light rays onto the retina at the back of the eye. With LASIK, an ophthalmologist creates a thin flap in the cornea using either a blade or a laser. The surgeon folds back the flap, and accurately remove a very specific amount of corneal tissue under the flap using an excimer laser. The flap is then laid back into its original position where it heals in place.

Specs removal operation for people whose eye sight is weak helps them get free from eye-glasses. For people who are nearsighted, LASIK is used to flatten a cornea that is too steep. Farsighted people will have LASIK to achieve a steeper cornea. LASIK can also correct astigmatism by shaping an irregular cornea into a more normal shape.

The leading eye care provider, Centre for Sight, is known for achieving excellence in eye care by providing specialized eye care, honest clinical opinion and latest technology. Eye care, to be truly effective, is all about harnessing state-of-the-art technology to be operated by the deft hands of experts.

Taking care of eyes in old age becomes all the more difficult. Most of the people after age 50 are likely to hear from their eye doctor, “You have cataracts.” A cataract is a clouding of the lens inside the eye, causing vision loss that cannot be corrected with glasses, contact lenses or corneal refractive surgery like LASIK. In cataract, there is a buildup of protein in the lens of the eye which makes it cloudy. This prevents light from passing clearly through the lens, thereby causing loss of vision.

Advancing age is a primary reason for cataract. With age, protein of the lens turns opaque. Other causes of cataract are metabolic disorders such as diabetes, excessive exposure to sunlight, lifestyle disorders like heavy alcohol consumption and smoking. Injury to the eye can also lead to clouding of the lens of the eye. When cataract forms, surgery is the only way to treat it. In cataract surgery, the surgeon removes the clouded lens and puts an Intra Ocular Lens (IOL) in your eye. Your vision will be as good as pre-cataract days, though you may need to wear glasses. Over the years, cataract surgery has moved from vision restorative to refractive surgery, so that you have reduced need of glasses.

A perfect combination of expertise of experienced surgeons and latest technology lead to a successful surgery. Centre for Sight is considered as one of the leading hospitals in India for cataract surgery. The hospitals are fully equipped with trained eye specialists for treatment of the patients.

Eye Conditions That Require Skill Ofan Eye Care Hospital

Eyes are the windows for any human being to the beautiful world. It is one of the most sensitive creations of nature and must be dealt with utmost care and compassion. Maintaining optimum vision should be the main priority of a human being. Proper attention should be devoted to the condition of the eyes and any diversion from the normal state should be brought to immediate notice of a certified specialist. The utmost importance of regular check up cannot be underestimated. It will ensure that your prescription stays updated, closely following the prevalent condition of the eyes. There are some conditions that normally do not show any early signs or symptoms, when they are in their initial stages. Only a routine checkup can rule out the probability of such a condition and help to avoid aggravation of the condition.

Routine eye checkup becomes mandatory once a person crosses 40 years of age, for preserving the eye-sight and maintaining it. There are many common symptoms that can be noticed in ageing adults which require expertise of some specialist in some good eye-care hospital to detect the problem on time. Some of these symptoms include difficulty in seeing objects that are at a closer distance or smaller prints, presence of tiny spots or specks that hover across the vision, entire area near the eye covered with cloudy areas, dryness, night blindness, redness, tearing, burning and itching. Apart from such problems, there can be eyelid problems as well, that include drooping of eyelids, inflamed eyelids, involuntary blinking and so on.

Headache can be also regarded as a symptom of eye problems and if it is not medicated on time then it can result in weakening of the eyes. Eye problems are also prevalent in children and the most common being astigmatism. Usually astigmatism goes undetected, which can cause further complications. Children can experience difficulty in reading or doing intricate work, squinting, frequent blinking and so on.

On some unfortunate events, Eye injuries could occur, which could cause unexpected loss of normal vision. They can include pain, flashing lights or loss of sight. Such situations can be regarded as medical emergencies and must be brought to the notice of a dedicated surgeon in some hospital who is capable of handling such traumatic situations and provide required aid on time with the help of skilled doctors and advanced technology.

How Does Drinking Alcohol Affect Your Eyes

Drinking alcohol can of cause effects to your entire body including your eyes. A low intake of alcohol shouldn’t cause you any health problems but drinking alcohol heavily can potentially cause health problems including harmful effects to your eyes.

Here are a few of the effects heavy drinking can have on your eye health.

Pupils

Alcohol can cause slow pupil reactions. It slows down the iris’ ability to dilate and constrict. This might not seem to be too much of a problem at first but if you have been drinking alcohol, even a small amount, and then drive your pupils won’t react as quickly to oncoming car headlights, therefore dazzling your vision which could cause an accident. So even if you have drunk alcohol and it is under the legal limit for driving and you feel fine to drive, think again about the other effects the alcohol is having on your vision.

Vision

Drinking alcohol can not only affect your pupils but also your general visual performance, especially if you have been drinking heavily. The alcohol can weaken the eye muscles which can cause blurred or double vision and also can cause delayed reactions.

Peripheral Vision

Not only can your general vision be affected after heavy alcohol consumption but your peripheral vision can change. Alcohol can sometimes lower your peripheral vision sensitivity and this can give the sensation of tunnel vision.

Contrast Sensitivity

Another way alcohol can affect your eyes is by making them less contrast sensitive. This means it can be harder to tell the difference between shade of grey.

Eye Lid Twitching

Eye lid twitching can be caused by many factors and one of these is a high intake of alcohol. If you suffer with eye lid twitching and drink heavily, try to lower your alcohol intake and see if your eye lid twitching improves.

Eye Dryness

A study carried out by the Hallym University College of Medicine indicated that drinking alcohol, even a small amount, reduced tear breakup time and induced tear hyperosmolarity which in turn can result in eye dryness.

Corneal Transplants; What Are They

Penetrating Keratoplasty (PK)
This type of cornea transplant replaces the full thickness of the cornea with a healthy and clear donor tissue and is required when a cornea has been severely damaged or disease, and where no other option of surgery remains. PK can be carried out under local or general anaesthetic and takes about one to two hours to complete. During surgery, a central 8mm button of cornea is removed and a similar sized button of the donor cornea is stitched in with tiny stitches. After surgery vision will stay misty and/or cloudy for a few days and will improve gradually for about 12-18 months. Individual stitches may be removed from three months after the surgery, but complete stitch removal is not performed until at least one year after the surgery. Following surgery, and once fully healed, around 75% of transplant recipients have adequate vision to drive legally, but to get the best results from vision, glasses or contact lenses may need to be worn.

Deep Anterior Lamellar Keratoplasty (DALK)
This type of cornea transplant is a partial thickness transplant and replaces the front 99% of the cornea with a donor cornea. Unlike penetrating keratoplasty, DALK keeps the back layers of the cornea, the Descemet’s membrane and endothelium layer, in place and it is used as an alternative to PK, when these back layers of the cornea are healthy. The surgery itself is carried out much the same as PK, but just less donor cornea is used. Again, stiches are used to keep the donor tissue in place, but as only part of the cornea has been replaced, healing and visual recovery are usually quicker than what are seen with PK. To get the best vision following surgery, glasses or contact lenses may need to be worn.

Endothelial Keratoplasty (EK)
This type of cornea transplant is a partial thickness transplant and replaces only the back layers of the cornea. Unlike to above two transplants, EK can be further split into two methods; Descemet’s stripping endothelial keratoplasty (DSEK) and Descemet’s membrane endothelial Keratoplasty (DMEK). Both DSEK and DMEK are very similar and the procedure to carry them out is the same, but DMEK differs as the donor cornea tissue does not include any stromal layer tissue. The consultant ophthalmic surgeon will decide which surgery is necessary, depending on the damage or disease that is present. EK transplants are used when there is a problem at the back of the cornea. To help keep the cornea clear, the cells lining the inside of the cornea pump fluid to stop the cornea from swelling, if there are not enough cells, due to disease or damage, then the cornea starts to swell and vision will become cloudy. The surgery is carried out differently when compared to PK and DALK; it will again be under either local or general anaesthetic but a very small incision is made between the coloured and white part of the eye. The eye surgeon removes the dysfunctional endothelial cells through this opening and a disc of donor cells is placed back inside the eye. The donor endothelial cells are pressed to the back of the cornea with an air bubble and the patient will need to lie still for about 1 hour following surgery to make sure the air bubble stays in place. Occasionally, a few stitches to close the incision may be needed. Vision will stay misty or cloudy for a few days, and will get better over 3-4 months, as with all types of corneal transplants glasses or contact lenses may be needed after surgery to get the best results from vision
